Which of the following is a solution to the system of two equations 4x + y = 51 and 2x – 6y = 6?

The solution to the system of equations given is:

y = 3x = 12

Step-by-step explanation:

First, we must see our two equations given:

4x + y = 512x – 6y = 6

We can use the reduction method, with this, we must eliminate a variable, in this case, de x variable, this can do multiply the equation 2 by (-2) and add the two equations:

(2x – 6y = 6)*(-2) = (-4x+12y = -12)

     3. -4x+12y = -12

Now, we operate the equations 1 and 3:

(4x + y = 51) + (-4x+12y = -12) = (13y = 39) "The variable x dissapears because   4x - 4x = 0"

     4. 13y = 39

We solve the equation 4 and obtain the value for "y":

13y = 39y = 39/13y = 3

With the value of "y," we can replace this value in equation 1 or 2 to obtain the value of "x," in this case, we're gonna use the equation 1:

4x + y = 514x + 3 = 514x = 51 - 34x = 48x = 48/4x = 12

In this form, we know the solution to the system of two equations is: x = 12 and y = 3.

Not sure what the question is?

It is 5.8 you add all of the up to equat 180 then solve the equation
